TGModule A-PM incorporates Ampliconyx patent protected, polarization maintaining ytterbium doped tapered double clad fiber (T-DCF) (US 8,433,168 B2, Japan 5390524, People’s Republic of China ZL 200880119087.7, EPO 08805462.2 pending). The fiber is pumped through the angle-polished anti-reflection coated endcap using customer provided free space optics. The fiber needs to be cooled during pumping. Heat sinks and water cooled fiber holding block are available as accessories. The thin input end of the fiber is a single mode fiber, and the input has an integrated cladding mode stripper (CMS).

• High-power gain fiber based on patented tapered double clad fiber (T-DCF)
•  Single mode output, M2 < 1.3
•  Large mode area, low level of nonlinear effects
